Selling my as new pristine 9.25 Hyperstar Ver4 in its Hard Case
$1900 posted to capital cities
Only used twice in the dome.
Also have an adaptor allowing the Hyperstar to be fitted to a C11 for $85 and an adaptor for a ZWO ASI 071 CCD camera $65.
The HyperStar 9.25 lens converts a standard Celestron 9.25" SCT from f/10 to f/2.2, making the system 25 times faster. That means 25-times shorter exposures! Now you can capture deep-sky images without guiding and without an equatorial wedge (in alt-az configuration). The HyperStar lens shortens the focal length of the telescope, giving a much wider field of view, and giving a greater tolerance of tracking errors, allowing for unguided, alt-az imaging.
